DC and AC load banks for industrial testing
Ensure your generators, batteries and UPS systems perform reliably every time.
Power Prove’s wide range of load banks help engineers test generators, UPS systems and battery networks safely and accurately. Each unit lets you simulate real‑world loads, monitor performance and ensure equipment operates as expected when it matters most.
Make load bank testing simple and reliable
Accurate and reliable
System-verified for consistent AC/DC performance
Flexible solutions
Choose from portable, fixed and custom systems
Operational support
Guidance for specifying, installing and using your equipment safely
Advanced control
Digital monitoring, data logging and precise load management
AC load banks
AC load banks are used for generator testing, UPS maintenance and validating AC electrical systems so they are ready for use in the event of a power outage. They apply a safe, predictable load so you can monitor voltage, current, frequency and power factor under controlled conditions.
Simulate real generator loads accurately
Measure voltage, current, and power factor
Suitable for field, workshop or integrated applications
Optional digital and remote control
DC load banks
DC load banks are used for battery discharge testing, UPS verification and validating DC power electronics. They allow you to apply a controlled DC load and measure system behaviour accurately.
Test battery strings and UPS under controlled load
Verify DC system performance before commissioning
Conduct portable or workshop-based testing
Capture test data for compliance or maintenance

If your project has non‑standard requirements, Power Prove can design a custom load bank built around your exact specifications.
Built for specific AC/DC voltages or interfaces
Can integrate with UPS systems, generators or monitoring platforms
Suitable for constrained or unusual installation spaces
Frequently Asked Questions
-
If you are testing generators or AC electrical systems, choose an AC model. If you are testing batteries, UPS systems, DC power supplies or solid‑state power control systems, choose a DC model. Power ratings and site conditions will help determine the exact model.
-
For generators, match the load bank to the rated kW output of the generator (e.g., 100kW generator → AC100).
For batteries or DC systems, size based on voltage and maximum discharge current (e.g., 600A systems → DC600/DC600‑PRO).
Our engineers can help you specify the right unit for your test profile.
-
Yes. Portable models like the AC100‑CPT or compact DC units deliver the same accuracy and load stability as fixed units, while offering mobility for field work or multi‑site testing.
-
Yes. The DUAL30 provides 31.5kW AC/DC testing capability in a single unit for low‑power applications or mixed‑system environments.
-
Yes. Models with Digiload digital control provide data logging, precision power measurement and networked control across multiple load banks. These can integrate with supervisory systems over Ethernet.
-
Yes. Radiator‑mounted AC load banks (10kW–300kW) can be integrated directly with a generator’s cooling system for permanent installation or packaged solutions.
-
All units are system‑tested and built with industrial‑grade safety features such as emergency shut‑off, robust enclosures, controlled airflow, thermal protection and (on selected models) digital monitoring with alarms.
